The Mazda RX-7 is a front-engine, rear-wheel-drive rotary engine powered sports car that was manufactured and marketed by Mazda from 1978–2002 across three generations, all of which made use of a compact, lightweight Wankel rotary engine. The first generation of the RX-7 was offered as two-passenger hatchback and as a 2+2 hatchback with occasional rear seats in some markets. The second generation was offered in a 2+2 hatchback as well as a two-door convertible bodystyle. The third generation of the RX-7 was offered as a 2+2 hatchback and was noted for its engine's sequential twin-turbochargers. The series 1 (produced from 1978–1980) is commonly referred to as the SA22C from the first alphanumerics of the vehicle identification number. In Japan it was introduced in March 1978, replacing the Savanna RX-3, and joined Mazda's only other remaining rotary engine powered products, called the Cosmo which was a two-door luxury coupé, and the Luce luxury sedan. The lead designer at Mazda was Matasaburo Maeda, whose son, Ikuo, would go on to design the Mazda2 and the RX-7's successor, the RX-8.[2] The transition of the Savanna to a sports car appearance reflected products from other Japanese manufacturers. The advantage the RX-7 had was its minimal size and weight, and the compact rotary engine installed behind the front axle, which helped balance the front and rear weight distribution, and provide a low center of gravity. In Japan, sales were enhanced by the fact that the RX-7 complied with Japanese Government dimension regulations, and Japanese buyers were not liable for yearly taxes for driving a larger car. The rotary engine had financial advantages to Japanese consumers in that the engine displacement remained below 1.5 litres, a significant determination when paying the Japanese annual road tax which kept the obligation affordable to most buyers, while having more power than the traditional engines having a straight cylinder configuration. In May 1980, Mazda introduced a limited production run of special North American models known as the Leathersport Models. This package was essentially an uprated GS model with added LS badges on each B-pillar, special stripes on the exterior, and LS-only gold anodized wheels (with polished outer face and wheel rim). All LS editions came equipped with special LS-only full brown leather upholstery, leather wrapped steering wheel, leather wrapped shift knob, removable sunroof, LS-specific four-speaker AM/FM stereo radio with power antenna (though listed as a six-speaker stereo, as the two rear dual voice coil speakers were counted as four speakers in total), remote power door side mirrors, and other standard GS equipment. Two primary options were also available; a three-speed JATCO 3N71B automatic transmission and air conditioning. Other GS options such as cassette tape deck, splash guards, padded center console arm rest and others could be added by the dealer. The LS model was only ever available in three different exterior colours: Aurora White, Brilliant Black, and Solar Gold. No official production records are known to exist or to have been released. This series of RX-7 had exposed steel bumpers and a high-mounted indentation-located license plate, called by Werner Buhrer of Road & Track magazine a Baroque depression. The Series 2 (produced from 1981–1983) had integrated plastic-covered bumpers, wide black rubber body side moldings, wraparound taillights and updated engine control components. While marginally longer overall, the new model was 135 lb (61 kg) lighter in federalized trim.[3] The four-speed manual option was dropped for 1981 as well, while the gas tank grew larger and the dashboard was redesigned, including a shorter gear stick mounted closer to the driver.[3] In 1983, the 130 mph (209 km/h) speedometer returned for the RX-7. The GSL package provided optional four-wheel disc brakes, front ventilated (Australian model) and clutch-type rear limited slip differential (LSD). Known as the FB in North America after the US Department of Transportation mandated 17 digit Vehicle Identification Number changeover. For various other markets worldwide, the 1981–1985 RX-7 retained the 'SA22C' VIN prefix. In the UK, the 1978–1980 series 1 cars carried the SA code on the vehicle VIN but all later cars (1981–1983 series 2 & 1984–1985 series 3) carried the FB code and these first generation RX-7's are known as the FB. The license-plate surround looks much like Buhrer's Styling Impressions.[citation needed] In Europe, the FB was mainly noticed for having received a power increase from the 105 PS (77 kW) of the SA22; the 1981 RX-7 now had 115 PS (85 kW) on tap. European market cars also received four-wheel disc brakes as standard.
